This workflow is ideal for users who need an automated solution to track ERC-20 wallet transactions. Features Automatic Monitoring: Executes every 5 minutes to capture new transactions. Customizable Filters: Customize tracking based on parameters like transaction duration and wallet addresses. Data Aggregation: Compiles transaction data into a single, structured list. Formatted Outputs: Presents processed data in an organized format. Telegram Tracking: Tracks wallet balances via Telegram notifications using the bot.

When a user sends the command {walletAddress} through the Telegram bot, the workflow queries the Tronscan API to determine if the provided wallet address is blacklisted. The result is then sent back to the user via the Telegram bot.

The workflow consists of four main nodes: Telegram Trigger Node: Listens for messages from the Telegram bot.
